Need help figuring out what size spokes you need for your BMX wheels? Here’s a BMX Spoke Calculator that should be able to help you figure out what size spokes you need for your BMX wheels.
Our friends at Manyfest BMX over in Poland have hooked us up with a BMX tool that we think will help out a ton of BMX riders. There’s nothing worse than breaking a bunch of spokes or planning to build up a new wheel set and not knowing what size spokes you need. Luckily, this super useful BMX Spoke Calculator is available to help you figure out just what spoke size you need! This already has a ton of different hubs and rims, but as always, there are new hubs and rims becoming available all the time. This calculator offers spoke sizes for 3-cross and 4-cross spoke patterns.
Need help building up your wheel? Here’s a video show you How To Build a 36-Hole BMX Wheel that should help.
Here’s How To True A BMX Wheel as well.
If you do not see your hub or rim listed, please let us know in the comments below and we’ll get to work on figuring out the sizes so we can help get you sorted out and back to rolling on your bike!
BMX Brands – If we don’t have your hubs or rims listed, please let us know! We want this to be the most complete and up to date BMX Spoke Calculator.
Are you stoked on this tool? Please give it a Share on Facebook, Twitter, etc. to help spread the word! We appreciate it.

Théo says
Hi,
looking for both front and rear RELIC Revolve hubs (with ODYSSEY Hazard Lite rims)
Thanks !
Nick says
Does x lacing change the spoke length?
Thanks,
Nick
Kurt says
Hey Nick, it does. Since you’re crossing over, your spoke has to reach a little further, so there’s a few mm additional.
Cameron says
Can you add the eclat cortex coaster please
Darrel White says
Team,
I appreciate the work done on this site, very helpful as you know. The spoke lengths I’m in need of are Eastern Ezra Freecoaster to 20” Rant Squad rim. Should be two different lengths as you know drive side/non-drive.
Thanks,
Darrel

Karl says
I have the Profile racing mini cassette rear hub And plan to lace it to an old school Alex Supra G rim with rim height of 20mm can somebody tell me what length spokes I need for drive side and non-drive side ?
Thank you much appreciated !
Jared Rablin says
I’ve got a Salt Everest wheel and looking at a BSD Revolution Hub, no clue what size spokes I’d need though.
Kurt says
Just sent BSD a message to get the measurements on the hub. I’ll see if I can find the ERD on the Salt Everest rim. I don’t usually get a response when I ask for this info from WTP, Eclat or Salt for some reason since I’ve tried a few times.
Bird says
Shimono hub sun rim ryno
Beezee says
I had a KHE Astern freecoaster hub, laced to a Proper rim and ordered the spoke length I got from the calculator, to lace 3 crossed to a cinema 777 rim. When I got the spokes and trued the wheel, spoke length was to big and surprisingly the spokes that were there with the Proper rim ended up being the right ones. Is there something wrong with the calculator?
Kurt says
Sorry about that. It’s possible the hub or rim information changed. We use the information supplied to us by the brand or what is listed online if the brand isn’t responsive to requests (Oddly it’s like pulling teeth trying to get hub specs and rim ERD info). A lot of the hubs and rims listed were supplied by Manyfest BMX as well before we uploaded this, so it’s possible the info changed since then. I’ll see what I can figure out.
Hector says
G-Sport Roloway cassette hub. Appreciate it
Postman559 says
Could you add the Animal SteamRoller 20” when you get the chance
Leon says
I have alienation 440 rim and I am getting tall order drone cassete hub and I dont know which size spokes I need, every time i check here the spoke lenght changes, could you help me?
Rob says
I think Flybikes has published the wrong flange distances on their Magneto specs. Don’t see how they could be 29DS and 19NDS. I’ve got a pair on order so am curious what the deal is…
Kurt says
Hey Rob,
I’m double checking but I got the numbers from David, the owner of Flybikes and designer of the hubs. I think it’s because the driver is a little different and sticks out further than a regular driver would, which decreases the offset of the flange.
Randy Callahan says
Alex g303’s. They are older i think, but they are the rims id like to put new hubs on so hope some calculator has them so i can reuse them!
Thanks
Frankie M says
Hi just came across your site and found one of my rims data. Eastern nitrous, however I also have some old school rims 1994 CMC which I can’t find any info for. As well as a pair of nos Japan Assess hubs (high flange) and another pair of Valisium hubs (again high flange). I am currently in the process of restoring two 1985 GT bicycles and any info on either the rims or hubs would be appreciated.

Ben says
Cinema FX2 freecoaster hub and mission engage hub. Also mission x7 rim
Eman says
Any chance of getting the new Eclat Seismic hubs added? The front is 36h, PCD: 38mm, Flange Offset: 26.75mm. But I can’t find any info on the rear. I’d love to lace up a new set at home for more experience but I’m no math wizard to figure out spoke lengths.
Eman says
Just heard back from Elcat about the Seismic cassette:
PCD: 45mm NDS
PCD: 51.5 DS
Flange (outside): 55.89mm
Maybe this helps? I only sort of understand what I’m looking at here.
Kurt says
Hey Eman,
I’ll email them and get some other details. Essentially I need the flange diameters and the offset (Flange to center of hub) on both sides and the spoke hole size. It looks like they gave you flange diameters and the length from flange to flange.
Eman says
Thanks Kurt, you rock!!
Colin says
It would be helpful if primo’s new remix v3 was on here, also if you could look into alien nation’s black sheep rim, here it says the ERD is 190, but some other sites say 195, though I’m not sure how big of a difference that is, I feel like it should be pointed out
Colin says
I meant 390mm and 395mm

Tony Hawkins says
So if my non-drive side is 188 mm but my drive side is 186 mm do I order 18 of each size or could I go in the middle and get 36 187 mm or just get all 188 mm or 186 mm

Chad Oliver says
Hey Rant Squad rims from Subrosa brand new cheapest ones on the market. Would be very helpful thanks
Scott says
The ERD for the G-Sport Birdcage is incorrect. It should be 383, not 390. All three G-Sport rims have a different ERD.
Kurt says
Hey Scott! Thank you! I have all three corrected. Those were a few that were already on the calculator when I was given it, so I assumed they were correct. That was my bad. I appreciate you letting me know!
Larry says
SORRY:! what NIPPLE length does this account for?

Kurtis Kunz says
Thank you, Kurt!

Some different measurement from profileracing website. For profile mini rear hub: drive flange diameter: 54. Non-drive flange diameter:43. Drive flange offset:28. Non-drive flange offset:33. Spoke hole diameter:2.5. Please update new measurements for them.
Kurt says
Thank you, Dong! I’ve updated the Profile Mini Cassette with the current measurements.
Korey says
Can you add the Sunday Cyclone Freecoaster to the list or let me know what size spokes I would need to fit an Odyssey Hazard Lite? I haven’t seen it on any spoke websites and I’m wondering if it’s because the hub is recent.
Kurt says
Hey Korey, I have added the Sunday Cyclone freecoaster hub, along with the Odyssey Clutch V1 and V2 since all three use pretty much identical hub shells (similar internals, too). Hope this helps!
dirty tony says
kurt dizzle!,

Luke says
it’s very nice you have provided this page but totally sucks since there’s no option to solve or update entered selection, rendering it completelyuseless.
Kurt says
Hey Luke, we’re working on updating the list. What hub and rim are you looking for? Once we have what people need, we can find the numbers we need for it.
michael courteau says
Hello i have a Hub Eastern Rear 9t is white hub no idea of the model !!!

We would need to know the model of the hub since all vary so much. If you can figure that out, we can get the flange diameters that we would use to calculate it.
